A sleep creep is someone who "creeps" out his/her significant other when shacking by doing such things as talking while sleeping, thrashing around, stealing the covers, making strange noises, sweating when its not hot, breathing hard, or opening his/her eyes while asleep.
Aaron is such a sleep creep, he dreamt that he was playing football and actually tackled Vicky in his sleep by rolling her on top of him and staring her in the face.

A dude who sends you pics from bed, usually trying to look sleepy and sexy at the same time, but it turns out creepy.
"Uuuugggghhh he sent me a pic of him in bed trying to look sexy and he just looked sleepy and creepy as fuck."
"Like a sleep creep?"
"Yes, exactly like that."
